The Toussaint Prison Experiment – Witcher 3: Blood and Wine Quest

This guide is a walkthrough of a side quest in the Witcher 3: Blood and Wine DLC. The guide is composed of a map, map legend, and walkthrough to show readers exactly where to go and what to do to complete the quest.

Background

At the Bastoy Prison Ruins in Toussaint South (#1), you’ll encounter a level 42 alp. Alps are vampires, so be sure to use Vampire Oil and Superior Black Blood to make the battle easier. Afterwards, you’ll find the corpse of a woman in the middle of the ruins. She’ll have a Clerk’s Diary and an Old Key in her possession. Reading the diary will trigger the quest.

Walkthrough

The diary will indicate that there’s a locked chest full of crowns somewhere in the ruins. You’ll find the chest on the eastern side. It’ll be a small chest right next to a large chest, so if you turn on your witcher senses, then it shouldn’t be too difficult to spot. Inside the chest, you’ll find around 400 crowns, some crafting supplies, and the diagrams for Toussaint Ducal Guard Captain’s Armor and Toussaint Ducal Guard Captain’s Trousers. Looting the chest will complete the quest.
